Speed and Velocity flashcard

Front

What do you need to calculate speed?

Back

You need to know the distance traveled and the time taken.

Front

What is the unit of speed?

Back

Speed is measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is speed in a specific direction.

Front

If a car travels at 70 miles per hour, how far will it go in 2 hours?

Back

140 miles.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is the average speed of a person who swims 105m in 70s?

Back

1.5 m/s.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

If a runner completes a 400m lap in 50 seconds, what is their speed?

Back

Speed = 400m / 50s = 8 m/s.

Front

What factors affect the speed of an object?

Back

Factors include the object's mass, the force applied, and resistance (like friction).

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.
